comments_template() generates bad theme-compat path

[dougal]

In the final fallback case of comments_template() it attempts to include theme-compat/comments.php, however, the path it generates is incorrect, because it fails to prepend ABSPATH.

This causes an error to be output to the page in older themes that rely on this feature.

Warning: require(wp-includes/theme-compat/comments.php): failed to open stream: 
No such file or directory in 
/var/www/vhosts/example.com/wordpress/wp-includes/comment-template.php on line 920

Fix theme-compat.php path

My bad.

Confusingly this all works in my test install as I must be lucky with the php path.

There are a number of places where the ABSPATH needs adding, working on this now.

(In [15433]) Fix the theme compat file require paths to be fully absolute so they don't rely on a particular php path to work. Fixes #14315 for trunk props dougal.

Erm, what is the purpose of error_log( $_template_file ); in [15433]?
